Reliable. According to the information of Tik Tok Lao Feng, Tik Tok Lao Feng said that the live broadcast was reliable. Laofeng Health Science has its own Tik Tok number, which exposes the first-hand information of the medical front to the public in time by sending short videos, conveys the image of medical workers to the public, and spreads medical health knowledge to the public, attracting the attention of many fans. Now I have my own fan base and opened a shop window to sell goods. Lao Feng's health science has played a great role, and Tik Tok also supports this material.
